Sonic's Evil Lair

Sonic's Evil Lair is the location of various events in Wario and Waluigi's Super Adventures Season 1, mainly episodes 1-2 and 1-3. It is where Flip and Flop kept Waluigi when he was kidnapped, and where Sonic ate french fries and created Shadow. Wario, Waluigi, Sonic, and Koopa eventually time traveled back to the Evil Lair to stop Shadow from being created, a mission which ultimately failed.
